Type: MCQ-numerical-Easy-Class 12
Turn ratio in a step-up transformer is 1 : 2. If a Leclanché cell of 1.5 V is connected across the input, what is the voltage across the output?
A
1.5 V
B
0.0 V
C
3 V
D
0.75 V
Correct Answer
Option B
Detailed Explanation
In a step-up transformer, the output voltage is the input voltage multiplied by the turn ratio. Thus, 1.5 V input results in 3 V output.
